Social Jetlag: Misalignment of Biological and Social Time

摘要: Humans show large differences in the preferred timing of their sleep and activity. This so-called "chronotype" is largely regulated by circadian clock. Both genetic variations clock genes environmental influences contribute to distribution chronotypes a given population, ranging from extreme early types late with majority falling between these extremes. Social (e.g., school work) schedules interfere considerably individual preferences population. Late largest work free days leading considerable debt on days, for which they compensate days. The discrepancy social biological time, can be described as 'social jetlag.' Here, we explore how quality psychological wellbeing are associated chronotype and/or jetlag. A total 501 volunteers filled out Munich ChronoType Questionnaire (MCTQ) well additional questionnaires on: (i) (SF-A), (ii) current (Basler Befindlichkeitsbogen), (iii) retrospective over past week (POMS), (iv) consumption stimulants caffeine, nicotine, alcohol). Associations chronotype, wellbeing, stimulant strongest teenagers young adults up age 25 yrs. most striking correlation exists smoking, significantly higher all ages (except those retirement). We correlations probably consequence jetlag, i.e., discrepancies rather than simple association different chronotypes. Our results strongly suggest that (and school) should adapted whenever possible.
